Mr. P u don't like the belt Not really a fan of them... way too pricey and you end up replacing the belt after time... the gear drive has been great for years now(one engine has 15 years on the gear drive) EDIT The belt drive was good for 1 thing in my opinion.. that was to help control harmonics on the engine.. I havent seen it to be worried about it but I dont build big power.. I just turn more RPM

Stutter boxes Kill chains I know you did not mention having one but..if you do then chains are wearable item that needs replacement Chain quality is not what it used to be either soak chain in oil day or two before install--it helps

I think if you checked most after a bit of use you might find most will give a little.
How much stretch are you talking?
Why toss "stroker" when the majority spin less or equal rpm vs other builds?
Just asking because it seems you just stumbeled on the reason people look for other options.
But ive ran rollmaster with a tensioner on all mine that stayed under 7500 and replace as/if needed. I know Stroker doesn't have to do with the stretch on our motors just stating they were stroker motors is all. My brothers .030 360 had the same chain same stretch in it. It's enough stretch that I think a guy could take a link out to make up for the difference. 3 seasons on a chain I know is plenty. Just was curious if anyone had better luck with other pieces.

I run the KB gear drive in all of my race stuff.. I do have a chain with a tensioner in my 416 street rod.. after the wear to get the edges of the chain down on the rollers it seems to be working fine.. I will find out when I see more than 500 miles on it Mr P Body, What KB gear drive are you running? I was on there website and they only list for big block applications. Did you buy your before they were discontinued? Thanks, Mark

Looks much like the KB unit.. basically the same mounting for the idler...I used a piece of paper to get the idler clearance.. very simple.. they have been on for years now ![wave wave](/ubbthreads/images/graemlins/custom/wave.gif)

What are the options for chain tensioners? Is the MP piece the only one available? I thought I read it wasn't as good as the stock tensioners from the magnum motors? If I recall the magnum one is the same.. I believe there was another company making the tensioner also. but I forget the name.. on a double roller chain it will wear quickly until the rollers come into contact.. then it slows right down... that tensioner was designed for the non roller chain like in the production silent chain ![wave wave](/ubbthreads/images/graemlins/custom/wave.gif)

I've had good results from pre-oiling the chain in synthetic gear oil for a day or two prior to install. It's such a small amount of oil that it hasn't had any bad effects that I can tell.
I use the same gear oil on my chainsaw chains, and it works WAY better, probably 2 or 3 times better than any other chain and bar lube I've ever tried. That's how I got the idea.
